Abstract
The method of making a non-metallic bearing assembly by bonding a first layer of uncured rubber that is wrapped on a mandrel to a fiberglass layer whose outer wrappings are impregnated with epoxy resin. The fiberglass outer layer is cured first to form a rigid outer plastic shell and then the uncured rubber is vulcanized to give an inner rubber sleeve whose inner periphery has polygonal contour which is the cross sectional configuration of the mandrel. An inner layer of fiberglass, cement impregnated, interconnects the fiberglass outer plastic shell to the inner rubber sleeve.
